Hot Keys

alt-1 – Load help

This week’s code sample is JAVASCRIPT based. It traps a keyup event in a web page that contains this code. The function then goes a step further and looks for the Alt key. Once we have the Alt filtered out we can begin to look for key combinations.

Below the code sample shows traping for numeric keys. The key code is actually an ASCII representation, so therefore you will need to know some common ASCII codes. Our example shows 48, 49, 50 being used. This translates to 1, 2, 3. So in short we are making a routine that will trap the following:

  • Alt-1
  • Alt-2
  • Alt-3

Important Note: Works with IE and FireFox

Try the Alt keys.
